Let's Kill Hitler to screen at the Edinburgh TV Festival

In the desperate search for Melody Pond, the TARDIS crash lands in 1930s Berlin, bringing the Doctor face to face with the greatest war criminal in the Universe. And Hitler. The Doctor must teach his adversaries that time travel has responsibilities - and in so doing, learns a harsh lesson in the cruellest warfare of all.

Sounds like it could be Davros considering he was basically "Hitler" in space. It might, and that's a very big might, be The Master. It could also be like the other comment and be someone from The War Games.

I've seen Christopher and His Kind, it was a brilliant movie... but it sort of screwed my image of the Doctor up. I don't blame Matt Smith, he's an amazing actor and all - but he did this movie and then went on to do series 6 of Doctor who. And I still love the Doctor!!

I'm not going to be able to make it to Edinburgh to see the screening of it - sadly. So I'll have to wait for the BBC to broadcast it.
